1 Claim.

The invention relates to fastener extractors and more particularly tostaple and thumb tack pullers.

One object of the invention i to provide a puller of the type abovedescribed in which a wedge blade is associated with a top binder meanswhich permit rocking of the staple, so that it may be readily pulledout, the blade being so constructed and arranged that it will handleseveral different size of staples.

A further object of the invention is to provide a staple puller madefrom a single piece of metal formed to provide a wedge blade and a pairof top binder jaws cooperating with said blade to wedge portions of thestaple between them and the blade, the base of the jaws providingfulcrum points to assist in prying the staple loose from its anchorage.

The invention further consists in the several features hereinafter setforth and more particularly defined by claim at the conclusion hereof.

In the drawings: v

Fig. 1 is a front elevation view of a puller device embodying theinvention showing its wedge blade inserted under the staple, parts beingbroken away;

Fig. 2 is a side elevation view showing the puller about to have itswedge unseated under the top of the staple, part bein broken away;

Fig. 3 is a side elevation view of the puller as shown in Fig. 1, partsbeing broken away;

Fig. 4 is an end elevation view looking in the direction of the arrowsshown in Fig. 3 showing one leg of the staple removed, parts beingbroken away;

Fig. 5 is a view similar to Fig. 4 showing the other leg of the stapleremoved, parts being broken away;

Fig. 6 is a view similar to Fig. 1 showing the application of the pullerto a thumb tack;

Fig. '7 is a side elevation view of the device shown in Fig. 6;

Fig. 8 is a view similar to Fig. 3 showing the start of removing a thumbtack;

Fig. 9 shows the device with the thumb tack removed.

Referring to the drawings, the puller embodying the invention comprisesa bar of fiat steel or other suitable metal formed to provide a handlel0 whose back end ll may be turned over and a front end portion bevelledto provide a wedge blade l2 which is bent up at an acute angle from theplane of the handle and further formed to provide a pair of top binderjaws l3, each jaw being bent up at (4 at an angle to theiiandle and tothe blade l2 and then extending forwardly at l5 substantially parallelto the plane of the blade l2, the said jaws also being bent inwardly orconverging inwardly toward each other to provide a top binder surfaceabove the blade [2. It is to be noted that the jaws l 3 are separatedfrom the blade portion l2 by sawing or slitting the front end of the barstock before bending the blade and the jaws to the desired shape.

To accommodate different sizes of staples the blade I2 is slotted at Hito one side of its center whereby three different sizes of staples canbe readily handled, two sizes being taken care of by the unequal spacingof the slot l6 relative to the width of the blade and the other size bythe whole width of the blade; however, staples whose leg spread isconsiderably wider than the width of the blade may be handled by thistoo] since it is capable of pulling out one leg of the staple at a time.

In use the blade I2 is positioned as shown in Fig. 2, and then worked inunder the bridge or top I! of the staple as shown in Figs. 1 and 2 withthe bridge lyin under the binder jaws l3, and then the handle isdepressed to lift the staple out of its anchorage, but if it will notcome readily, then it is canted first to one side and then the other asshown in Figs. 4 and 5 to withdraw the legs from the material into whichthey have been driven. In canting the puller the corner l8 between thebridge l1 and the staple leg l9 being withdrawn wedges or is clinchedbetween the blade l2 and the lower inner edge of one of the binder jaws[3 as shown in Fig. 4 while the part 20 at the edge of the base of theother jaw acts as a fulcruming point about which to swing or cant thetool to remove the leg l9 and that this same action takes place inremovin the other leg 2| of the staple as shown in Fig. 5, the wedgingor binding of the corner 22 between the blade and the other jaw thentaking place while the tool fulcrums about the part 23 at the base ofthe opposite jaw.

The tool may also be used for the placement and removal of thumb tacks.In removing a thumb tack 24 as shown in Figs. 6 to 9 its action isgenerally similar to the usual tack puller, the wedge blade I2 beinginserted under the head of the tack 24, so that the slot l6 alines withthe shank of the tack. However, the top binder jaws I3 projecting a theydo over the head of the tack act to retain the tack in the pulling endof the tool until it is extracted, and for placement of thumb tacksthese binder jaws form a back stop for the head of the tack, so that itmay be pressed down into the material to be fastened to the desiredanchoring surface.

I desire it to be understood that this invention is not to be limited toany particular form or arrangement of parts except in so far as suchlimitations are included in the claim.

What I claim as my invention is:

A tool of the character described, comprisinga wedge blade having a slotoffset to one side of the center of said blade to accommodate staples ofdifferent sizes, and binder means above the blade between which and theblade an exposed portion of the staple i wedged during the removal ofthe staple.
